# Fix typos, update traditions, add new cultural tradition, and expand character names

## Changes:

- Corrected building identifier:
  - `madird_university_01` → `madrid_university_01` in building definitions and province history.
- Fixed localisation typos:
  - `leuven_universtiy_01_desc` → `leuven_university_01_desc`
  - `Fortress of Giblraltar` → `Fortress of Gibraltar`
- Replaced outdated tradition `tradition_welcoming` with `tradition_esteemed_hospitality` in multiple cultures.
- Added new cultural tradition `tradition_life_is_just_a_joke` with:
  - Character modifiers (stress reduction, prestige gain)
  - AI behaviour preference
  - Cost and parameters definitions
- Expanded male and female character name lists in `NEOW_novelist.txt` to add more diversity and flavour.
- Updated descriptions for University of Montpellier and Madrid University to reflect accurate historical names and details.
